Zac Efron & Taylor Swift: Duet on Ellen!

Zac Efron and Taylor Swift pull out their guitars and sing a duet on The Ellen DeGeneres Show, airing today!

The 24-year-old actor and his co-star from The Lorax chatted with Ellen about their dating rumors and what they really did for Valentine’s Day last week.

Taylor, 22, shared, “We are not a couple. He’s awesome, we are not a couple though. You hear people get together when they’re shooting movies, co-stars. But not like animated co-stars. You know what I’m saying. Oh my god, as we were recording our voiceovers on separate coasts we really connected.”

After hearing how Taylor spent her V-day, Zac said, “That’s so different than what single guys do. I went to a screening of a film that I did called Liberal Arts. Then cooked some dinner with a friend.”
